More information is needed, I'm afraid to say. Which versions of
Kermits are being used? The VERSION command and the startup herald will
show that. Flow control *must* be used, particularly going to the VAXen.
Since hardware flow control is difficult to achieve on VAXen you are stuck
with XON/XOFF, so be sure the VAX side can send it (see your VAX system
manager). Then do not unprotect XON/XOFF control codes in Kermit packets
because that will let data mistakenly act as flow control bytes.
Finally, examine the PARITY situation. If parity is in use be
sure to tell both Kermits about it, else you will lose the high bit of
bytes and the transfer will fail.
